What happens when too much lime is applied?
Soil pH and micronutrient availability are interrelated. Too much lime can raise soil pH to a point where micronutrients become unavailable to plants. Micronutrients affected by pH include iron (Fe), manganese (Mn), zinc (Zn) and, to a lesser extent, copper (Cu). Problems caused by applying too much lime are more difficult to correct than those that result from having applied too little. You can always apply more lime, but you cannot remove it if you put out too much.

A: When used as specified on the label, pelletized lime is just as effective as powdered lime. Pelletized lime contains finely ground dolomitic lime bound in pellet form. In contact with water, the pellets disintegrate and release the enclosed lime. Pelletized lime is more expensive but easier and less messy to apply than powdered lime. To many homeowners, it is well worth the extra cost. Q: Why is it important to mix lime into the soil? A: Lime is only slightly solub
